Growth adaptabilities of Zizania latifolia in different artificial wetlands

Zizania latifolia mainly grows in the land/inland water ecotones of river channels and lowland swamps of Lake Taihu Basin.Its growth condition is representative in this area.Four different environment conditions such as implanted ecological filter bed,biological oxidation pond,subsurface flow and surface flow integrated artificial wetland and horizontal subsurface flow artificial wetland have been designed based on the status of land/inland water ecotones of river channels.The growth adaptabilities of Z.latifolia in different environments were studied so as to provide a scientific evidence and technical support for establishment and restoration of the degraded vegetation communities of land/inland water ecotones of river channels.The results showed that Z.latifolia was able to adapt to different growth environments such as zeolite matrix and hydroponics;the growth rate and luxuriance degree differed among substrates.
